I'm trying to make a mod that would turn "BlockA" into "BlockB", but I dont see that option in the GameRegistry, there is only "BlockA" to "ItemA" and "ItemA" to "ItemB"
GameRegistry.addSmelting(Block input, ItemStack output, float xp) : void
GameRegistry.addSmelting(Item input, ItemStack output, float xp) : void
GameRegistry.addSmelting(ItemStack input, ItemStack output, float xp) : void
